What’s the dirt on lipid biomarkers and soil pH?

Previous studies have shown that bacterial membrane lipids are sensitive to changes in environmental parameters such as soil pH (e.g. Weijers et al,. 2007) and have enabled the development of the CBT index, a soil pH proxy based upon the number of cyclopentane rings within these lipids. Although the CBT proxy has evolved in recent years (see De Jonge et al., … More What’s the dirt on lipid biomarkers and soil pH?
